    摘要: A method of production of an electric contact including a contact base member of one metal and a contact member of another metal of hardness lower than that of the contact base member joined to the contact member at one end portion thereof, with the method comprising the steps of forming a blind hole at the one end portion of the contact base member and applying pressure simultaneously to the contact base member and the contact member after the contact member is inserted and filled in the blind hole, to thereby cause the metals of the two members undergo plastic deformation to join them together in intimate contact with each other.

    摘要: A method of production of a cylindrical body from a sheet of steel formed at opposite sides with projections and cutouts complementary to each other. The method comprises the steps of rolling the sheet of steel and inserting the projections in the cutouts to provide a cylindrical blank, and compressing at least one of inner and outer peripheral surfaces of the cylindrical blank in a radial direction to reduce the thickness of the cylindrical blank and to stretch a portion of the cylindrical blank in an axial direction whereby the projections inserted in the cutouts can be brought into intimate contact with each other at jointed portions.

    摘要: A magneto for a motor vehicle includes a flywheel having an exciting source and adapted to rotate in timed relation to the engine, and an armature to be excited by the exciting source. It also comprises an elastic steel cover on at least the inner surfaces of its magnet elements, so that the elements are pressed against, and positioned with respect to, the inner surface of the rim of tray-shaped flywheel.
